GAS-HEATER.

Loeaerzf To all whom t may concern Be it known that l, JESSE T. RnzNoR, a citizen of the United States, and a resident of Mercer, in the county of Mercer and State of Pennsylvania, have invented certain new and useful Improvements in Gas- Heaters, of which the following is a speciiication.

The invention relates to gas heaters.

One object of the invention is to provide a sheet metal gas heater with a top construction which adds to the strength, rigidity and finish of the upper portion of the heater.

The invention is `also directed to the specific construction of the upper corners of the heater.

The invention also relates to other features of the heater which are clearly set forth in the accompanying claims.

As showing a specific embodiment of the invention, reference is made to the drawings forming a part of this specii'ication, in which Figure 1 is a front elevation of the heater, partially broken away. Fig. 2 is a sectional view taken on the line 2 2 of Fig. 1 or on the line 2 2 of Fig. 4. Fig. 3 is a sectional view taken on the line 3 3 of Fig. 2. In Fig. 3 the legs which support the casing have been removed. Fig. 4 is a rear elevation of the heater. Fig. 5 is a partial vertical view showing in full size the corner A. in Fig. 4. Fig. 6 is a partial plan view showing in full size the corner A in Fig. 4. Fig. 7 is a partial plan view showing the top member of the heater broken away so as to expose the upper ends of two of the vertically extending members of the casing of the heater and a part of the inner corner member. Fig. 8 is a view showing a portion of the top member of the heater in place on the upright side and back members of the heater casing, said top member and the upright members being broken away so as to show the bent corner joint construction between the sides and back. Fig. 9 is a view taken on the broken line 9 9 of Fig. 6 looking in the direction of the arrows. Fig. 10 is a perspective view showing the under side of the outer corner member. Fig. 11 is a perspective view showing the under side of the inner corner member. Fig. 12 is an enlarged sectional view showing the reinforcing bar in place in beaded portions at the bottom edge of the upright members and Specicaton of Letters Patent.

also showing partially in section one of the supporting legs at the rear of the heater. F 1g. 13 1s a View showing only a portion of the upright side and rear members and a portion of the reinforcing bar or rod located in the lower beaded portions thereof. Fig. 14 is a view taken on the line 14 14 of Fig. 4 and shows only a part of' the lower beaded portions of the upright members and the reinforcing rod in place in the beaded portion.

The heater comprises the casing B, the burner C, the reflecting member D, the inner roof or baflie plate E and the casing supporting legs F. The casing is formed of vertically extending sheet metal members which constitute the front, sides and back thereof and a horizontal flat sheet metal top member H. The sides extend at right angles to the front and back members and provide a casing having a rectangular cross section. The burner C, reflecting member D and the baffle plate E are all located within the casing and are arranged so that the heat is reflected through the front of the heater which is open.

The sides of the casing are designated bv the reference characters b2 and 54 and are secured to the back 3 by bending the metal at the rear edges of said sides and at the side edges of the back to form the interlocking joint clearly shown in Figs. 3 and 8. At the forward edges of the sides Zig and 6^* the metal is first bent inwardly toward the companion side and then rearwardly so as to form vertical columns b5 and b at the opposite front corners of the heater. To the forward edges of' the sides there is secured by riveting the opposite side edge portions of the upper and lower front members ZJ and b respectively in which the metal is bent rearwardly to form the flanges or laps ba" on the upper member and bx on the lower member. The lower edges of the vertically extending front, side and back members are provided with the horizontally extending beaded portions 67, 68, b9 and Z910, which are open at the inside of the casing and in these beaded portions there tightly lits a rod 7912 bent to Jform a rectangle, as shown in Fig. 14. This rod serves to brace, strengthen and add rigidity to the lower portion of the heat-er; and the ends of the rod may be welded together if desired or the rod may terminate and the ends may meet between the corners as at substantially the middle portion of the sides. The casing is supported at the co-rners on the legs F which are provided with beaded portions which fit over both the beaded portions of the sides and the beaded portions of the front or back members. Each of the legs is riveted to the side and the front or rear member with which it fits. The top edge of the front, side and rear members, namely members b, b2 3 and b4, are provided with beaded portions Z213, b1, 7015 and 516. The top member H is also provided with beaded portions g', g2, g3 and g* that fit the outside of the beaded portions ot' the upright'casing members.

At each of the corners at the top of the heater there is an inner plate g5 having rectangularly arranged beaded port-ions g and (/7 and an outer member or plate g8 having rectangular-ly arranged beaded portions 99 and gm. The beaded portions g and (/T of the inner corner member fit within the beaded portions at the tops of the front, sides and back members and the inner part of the beaded portions g" and g1 of the outer corner member fit the outside of the beaded port-ions at the corners ot' the top member H. Both the inner and outer corner members g5 and gs are provided with openings g for t-he passage of' the screw g which is provided with the nut or cap g1g. The openings g in the inner and outer co-rner plates are located so that when the screws pass therethrough said plates can be drawn toward each other, whereby the top member and t-he upright portions at the front, sides and back of the casing will be securely and firmly clamped and held together, thus affording a rigid, simple, compact and neat construction for the top of the heater.

The burner C comprises a tube c having a series of perfor-ations at c2 for the passage of the gas which is to be consumed. This tube extends the full width ot' the heater and passes through and is supported by the sides b2 and o" thereof. The side is provided with an opening o adjacent to the burner tube through which a lighted match may be passed when the heater is to be started.

The refiecting member D comprises fanshaped members cl located within the casing at opposite sides of the heater, and a curved reflecting plate (Z2 connecting the fanshaped members. This reflecting member is secured to the casing by the rivets c4 (see Figs. 1,2 and). The burner tube 0 is located m the rear of the casing near the upper end of the curved reiecting plate cl2 and in front thereof.

The inner roof or baffle plate member E is locatedabove the burner and extends the full width of the casing. This roof or battle is secured to the sides and back of the casing and extends forwardly and upwardly, terminating short, however, of the front upper member The casing is provided at the back with the vent opening Z) to permit the escape of gases that pass between the roof member and the front upper member b to the space between the top H and the roof member.

It is o-bvious that various forms and modiications may be made without departing from the spirit and scope of the invention.

That I claim is:

l. A gas heater having vertically extending members rectangularly arranged and each provided with a beaded portion at the top, a top member provided with beaded portions which fit the outside of the beaded portions on the vertically extending members, an inner corner member fitting within the last mentioned port-ions, an outer cap member fitting upon the outer part of the beaded top member, and means for holding the inner and outer corner members together whereby they will hold the vertically extending members and the top member firmly together.

2. A gas heater having sheet metal vertically extending front, side and back members arranged at right angles to each other, a top member, an inner corner member, an outer corner member and a screw member, the upper edges ot' the front, side and rear members being beaded, the outer edges of the top member being beaded and fitting with the beaded edges of the front, side and rear members, the inner corner .member fitting the interior beaded portion of the upright members, the outer' corner member fitting the exterior of the beaded portion of the top member and the screw means passing through the inner and outer corner mem bers whereby they may be drawn toward each other and serve as clamping means to hold the top member and the vertically extending members together.
